One of the new features of Gannet 3.0 is the ability to process and quantify edited MRS data acquired by HERMES (1–3). Here is a quick "getting started" tutorial on running a GABA-/GSH-edited HERMES dataset:

Download Gannet 3.0, placing the master folder at the top of your MATLAB's search path.

Open GannetPreInitialise.m.

Set MRS_struct.p.target to 'GABAGlx' and MRS_struct.p.target2 to 'GSH' (these are the defaults).

Set MRS_struct.p.ONOFForder to 'offfirst' if running a Philips HERMES dataset, or 'onfirst' if running a GE HERMES dataset.

Set MRS_struct.p.water_removal to 1 (this is the default).

Set MRS_struct.p.AlignTo to 'SpecRegHERMES'.

Set MRS_struct.p.HERMES to 1.

Save your changes.

Change your working directory to where your HERMES dataset is saved.

To run GannetLoad on:

GE data, run: MRS = GannetLoad({'HERMES_1.7'});

Philips data (with a water reference), run MRS = GannetLoad({'HERMES_1_act.sdat'},{'HERMES_1_ref.sdat'});
